Cancer Patients and the Internet: a Survey Among German Cancer Patients.

An increasing number of patients and relatives use the Internet to get additional or initial information about their disease. The aim of the study was to reevaluate the Internet usage among German cancer patients. Using a standardized questionnaire, we did an anonymous survey on patients attending a series of lectures on complementary medicine in 2014. We received 255 questionnaires. Nearly 80 % of the participants stated that they used the Internet to read up information about health or medicine issues. There was no significant difference regarding gender, age, or status (patient, current treatment/former treatment; relatives). Most users use the Internet in order to get additional information after a consultation with a physician (82.2 %). Important qualities from the view of the patient are a trustable source (65.3 %), information from experts (59.6 %), and actual information (52.8 %). There is an increasing number of patients in Germany looking for information in the Internet mostly in the intention of getting additional information. Yet, as the quality of information is heterogeneous, false information may lead to distrust in the doctor or wrong decision-making. Accordingly, organizations working on improving quality of cancer care should engage in conveying comprehensive and actual information adapted to the needs of patients. Physicians should know trustful websites for referral of patients.

Visualizing risks in cancer communication: A systematic review of computer-supported visual aids.

OBJECTIVE: Health websites are becoming important sources for cancer information. Lay users, patients and carers seek support for critical decisions, but they are prone to common biases when quantitative information is presented. Graphical representations of risk data can facilitate comprehension, and interactive visualizations are popular. This review summarizes the evidence on computer-supported graphs that present risk data and their effects on various measures. METHODS: The systematic literature search was conducted in several databases, including MEDLINE, EMBASE and CINAHL. Only studies with a controlled design were included. Relevant publications were carefully selected and critically appraised by two reviewers. RESULTS: Thirteen studies were included. Ten studies evaluated static graphs and three dynamic formats. Most decision scenarios were hypothetical. Static graphs could improve accuracy, comprehension, and behavioural intention. But the results were heterogeneous and inconsistent among the studies. Dynamic formats were not superior or even impaired performance compared to static formats. CONCLUSIONS: Static graphs show promising but inconsistent results, while research on dynamic visualizations is scarce and must be interpreted cautiously due to methodical limitations. PRACTICE IMPLICATIONS: Well-designed and context-specific static graphs can support web-based cancer risk communication in particular populations. The application of dynamic formats cannot be recommended and needs further research.

What cancer patients find in the internet: the visibility of evidence-based patient information - analysis of information on German websites.

BACKGROUND: The internet is an easy and always accessible source of information for cancer patients. The aim of our study was to evaluate the information provided on German websites. MATERIAL AND METHODS: We developed an instrument based on criteria for patient information from the German Network for Evidence-based Medicine, the Agency for Quality in Medicine, HONcode, DISCERN, and the afgis. We simulated a patient's search and derived the websites for evaluation. We analyzed the visibility of each website and evaluated the websites using the developed instrument. RESULTS: We analyzed 77 websites. The highest visibility index was shown by 4 profit websites. Websites from professional societies and self-help groups have low rankings. Concerning quality, websites from non-profit providers and self-help groups are on top. Websites with a profit interest have the lowest average score. CONCLUSIONS: A discrepancy exists between the visibility and the quality of the analyzed websites. With the internet becoming an important source of information on cancer treatments for patients, this may lead to false information and wrong decisions. We provide a list of suggestions as to how this risk may be reduced by complementary information from the physician and from trustworthy websites.

[Survey on information needs of cancer patients and their relatives in Germany]. / Der Informationsbedarf von Patienten mit Krebserkrankungen in Deutschland - eine Befragung von Patienten und Angehörigen.

INTRODUCTION: Cancer patients generally have a great need for disease-related information. They prefer to be informed personally by the attending doctor. Yet, they also use other sources, mostly from medical laypersons or public media. The goal of our survey was to obtain insight into information patients get and their requirements regarding information. METHODS AND PARTICIPANTS: Using a standardized questionnaire, we conducted a survey on 226 patients and 32 relatives, who attended meetings providing information for cancer patients. RESULTS: Patients were generally content or highly content with the information they got. The direct consultation with the doctor is the most important source of information especially for older patients. Information by other patients and self-help groups rank second, followed by internet and online chats, which both are of minor importance for patients older than 60 years. From the patients' point of view, sources of information should be individualized and comprehensive, provided by experts and allowing for questions. Patients prefer one constant person for communication. Remarkably, empathic communication was not rated as important. Age and gender are not associated with these preferences for these characteristics of sources of information. DISCUSSION: Patients' and relatives' desire for an individualized, comprehensive counseling with high expertise provided by one person points to the limits of resources of the health system. The importance of additional information material will rise accordingly. This material should be tailored to the needs of diverse patient groups.
